I am pursuing my PhD in Life sciences. I wanted to continue my career in Public health. Please guide me how to get into the public health sector. Is there any post doctoral opportunities available in public health?
It depends, in part, on your area of expertise in life sciences. You may qualify for work in a public health department or one that addresses one or another aspect of health research. And certainly, a year's study for a masters of public health would put you, with the PhD, directly in line for work in this area.
But do note what you qualify for, and what is available, will be highly dependent on where you and and the structure of health services in that country or region. So outsides from other nations will be of limited help in this area.
